Description
The present invention relates to a kind of used adsorption plant of adsorbing and extracting device that light sheet is held and extracts with adsorber.
The adsorbing and extracting device that the light sheets such as printed circuit board base board that stacked on top of one another extract from top one piece of one piece of ground, have now all and on the support unit that extracts frame, adorning magnetic sheet, and below magnetic sheet, by having the magnet type support of permanent magnet, adorning some vacuum adsorption type adsorbers down.
Existing magnet type support, its rack body is made of the synthetic resin material of nylon and so on, is embedded with permanent magnet in the upper end of this rack body, and adsorber, is being adorned in magnetic sheet to adjustable positions by support by the suction of this permanent magnet to magnetic sheet.
In this magnet carrier, permanent magnet and magnetic sheet relative to end face and end face join, adsorber is to be fixed in magnetic sheet by the suction that magnetic force produced between them by support.
But the structure of existing support is to bury one or several permanent magnets underground in the upper end of its main body, and permanent magnet is disposed at the field except that the outer peripheral portion of support upper end.Therefore, compare with the size of this support upper end diameter direction, the interval of permanent magnet two ends on this diametric(al) is shorter, and when being subjected to lateral external forces in the adsorber bottom or centering on the external force of longitudinal axis rotation, adsorber may be unstable, produces inclination or rotation.So, because the posture instability of adsorber may not be held securely so be adsorbed object, adsorber may split away off from magnetic sheet together with support.
If with the enlarged areas of support upper end, bury powerful permanent body in the above underground with big adsorption area, then just can fully resist laterally or the external force of hand of rotation.
But, in this case, to compare with the size of adsorber, it is very big that support becomes, so be difficult to practical application.Particularly below magnetic sheet, disposing a plurality of adsorbers, and carry out under the sharply tuned situation along the plane of magnetic sheet being necessary position each adsorber, because the support of each adsorber of supporting can produce conflict each other, so the space between each adsorber can not be transferred very for a short time, each adsorber is carried out the position adjustment just have any problem.Therefore, support being done big itself is just limited, is can not fully resist laterally or the external force of hand of rotation.If strengthen the suction of permanent magnet, then support comes off and will have any problem from magnetic sheet, and the adsorber fine position bothers all the better.
The present invention develops for the problem that solves above-mentioned existing existence, its objective is to provide a kind of support of as far as possible avoiding to maximize, support is firmly fixed on the magnetic sheet by the magnetic force of permanent magnet, even adsorber be subjected to laterally or the external force of hand of rotation do the time spent, can prevent that also adsorber from tilting or come off, and can carry out sharply tuned adsorption plant to the position of adsorber easily.
The present invention can realize above-mentioned purpose.

Each stabilizer foot 56 usefulness non-magnetic material is made, and for example uses with the same synthetic resin materials such as nylon of support 39 to constitute, and end face is being buried permanent magnet 57 underground thereon.Periphery at base portion 52, dispose four stabilizer foots 56 in that circumferencial direction is separated by a certain interval, radially outward outstanding from base portion 52, when permanent magnet 44 sorptions of base portion 52 are below magnetic sheet 38, by link slot 58 be connected projection 59 and can freely get with taking off and be connected on the base portion 52, permanent magnet 57 and magnetic sheet 38 are joined.
The permanent magnet 57 of stabilizer foot 56 is cylindrical, is embedded in the center upper portion of stabilizer foot 56, and is the same with the permanent magnet 44 of base portion 52, and its upper surface is more outstanding than the upper surface of base portion 52.It is the S utmost point that permanent magnet 57 can be magnetized to the upper surface respectively, and the lower surface is the N utmost point, or the upper surface is the N utmost point, and the lower surface is the S utmost point.
Like this, the permanent magnet 44 of base portion 52 and the permanent magnet 57 of stabilizer foot 56, the polarity of its upper end magnetic pole is opposite, and such permanent magnet 44,57 sorptions are below magnetic sheet 38 time, just forms from permanent magnet 44 through magnetic sheet 38, permanent magnet 57 again to the magnetic wires of permanent magnet 44.
Each aspirate tube 47, through near the leadout hole 43 the adsorber 7, below magnetic sheet 38, lead to support unit 37 above, and be fixed in the communication port 60a that the distribution of extracting frame 36 is connected tool 60 and be connected.Distribute connection tool 60 left and right directions on extraction frame 36 to be equipped with four, be arranged at these four and distribute the communication port 60a that connects tools 60 to be connected with the aspirate tube 47 of each adsorber 7.Four distribute to connect that tool 60 is unified to be connected with the vacuum source do not expressed among the figure.Adsorber 7 is corresponding with the both ends of each printed circuit board (PCB) 3 length direction (extraction direction), two one group ground configuration.
Travel mechanism 9 has bay-lift of leap 5 and feeding belt conveyor 2, the pair of guide rails up and down 62 of configured in parallel above it, also can be by pair of guide rails 62 supportings in the movable frame 63 of feed direction slip, be disposed between the pair of guide rails 62, drive the feeding cylinder 64 that movable frame 63 is slided to feed direction along guide rail 62, can slide up and down to the crane 66 that is supported on movable frame 63 and on its bottom, fixing the central portion that extracts frame 36 left and right directions by guide mechanism 65, and drive the lift cylinder 67 that crane 66 moves up and down along guide mechanism 65.
On bearing support 68, be provided with the killer 72,73 that restriction movable frame 63 moves at the two ends of guide rail 62.Killer 73 can suitably be adjusted its position according to the length of printed circuit board (PCB) 3 by being arranged on the bearing support 68 with extracting the direction adjustable positions.
Have the multiple row pay-off of said structure, as described below, by feeding belt conveyor 2 multiple row printed circuit board (PCB) 3 is flowed to next procedure simultaneously.At first, interval constraint plate 32 utmost points are adjusted, simultaneously support unit 37 is adjusted with respect to the overhang of extraction frame 36 and the position of each adsorber 7 below the support unit 37 according to the width of printed circuit board (PCB) 3.
When support unit 37 is adjusted, after having removed fixing tool 41 pairs of support units 37 fixing, according to the size of printed circuit board (PCB) 3, allow support unit 37 and slide with respect to the tool 40 of being received that extracts frame 36, make that the rear end of support unit 37 is roughly consistent with the rear end of printed circuit board (PCB) 3.Roughly with after the rear end of printed circuit board (PCB) 3 is consistent, operating handle 42 fixedly tool 41 is fixing in the rear end of waiting until support unit 37 then, by this fixedly tool 41 support unit 37 be fixed on extract on the frame 36.
Like this, owing to can suitably adjust the overhang of support unit 37 according to the size of printed circuit board (PCB) 3, therefore during mounting substrate duplexer 4, protrude in the support unit 37 that extracts frame 36 and can not cause trouble on bay-lift 5, loading operation can successfully be carried out.
Next, under the situation of the aperture distribution situation of considering printed circuit board (PCB) 3, the position of each adsorber 7 is adjusted, so that absorption cake 46 is facing to the minimum part of aperture.
In this case, the permanent magnet 57 of the permanent magnet 44 of support 39 base portions 52 of each adsorber 7 and the stabilizer foot 56 of its periphery be adsorbed on magnetic sheet 38 below, adsorber 7 by the magnetic force of this permanent magnet 44,57 be fixed on magnetic sheet 38 below, therefore can easily adjust the position of absorption cake 46, make it face toward the part that printed circuit board (PCB) 3 does not have aperture, can adjust in direction arbitrarily easily with simple structure.
Because adopted the big or small roughly the same of magnetic sheet 38 and bay-lift 5, the permanent magnet 44 of support 39 be adsorbed on this magnetic sheet 38 below, thereby the structure that adsorber 7 is fixing, so can below magnetic sheet 38, in any direction adsorber 7 be adjusted according to the aperture distribution situation of printed circuit board (PCB) 3.
Allow the permanent magnet 44 of support 39 base portions 52 be adsorbed on the magnetic sheet 38 though adopted, thereby with adsorber 7 adjustable positions the structure of being fixed, because the periphery at support 39 base portions 52 has four stabilizer foots 56, therefore can lean on these four stabilizer foots 56 improve supports 39 laterally with stability around longitudinal axis hand of rotation, even the bottom of adsorber 7 is subjected to laterally or the effect of hand of rotation external force, can prevent also that support 39 and adsorber 7 from being done, inclination and rotation etc.
Particularly, because on each stabilizer foot 56, be provided with permanent magnet 57, this permanent magnet 57 is adsorbed on the magnetic sheet 38 of support unit 37, so with the stabilizer foot 56 of this permanent magnet 57 not, just allow it compare with the structure of being abutted against below of magnetic sheet 38, the bed knife of 39 pairs of magnetic sheets 38 of support greatly improves, and the stability of support 39 also is improved.
Because the big permanent magnet 44 of central authorities is adsorbed in magnetic sheet 38, four little permanent magnets 57 around this permanent magnet 44 also are adsorbed in magnetic sheet 38 simultaneously, therefore for example when adsorber 7 is subjected to the lateral external forces of direction shown in the arrow a of right-to-left for example (with reference to Fig. 8), external force will overcome the suction of central permanent magnet 44 and the suction of four permanent magnets 57 on every side thereof, and just can make support 39 is that fulcrum tilts with the permanent magnet 57 of the stabilizer foot 56 on the left side.
Therefore, fulcrum when tilting leave significantly support 39 the center and in outside, the magnetic force of permanent magnet 44 and permanent magnet on every side 57 thereof can play the support 39 bevelled effects that stop, improve the stability of support 39 and adsorber 7, prevent to tilt, come off from magnetic sheet 38 etc. because of lateral external forces makes adsorber 7.
Because support 39 projects upwards with the permanent magnet 44,57 of stabilizer foot 56, so each permanent magnet 44,57 can directly be adsorbed in the magnetic sheet 38 of support unit 37.And since stabilizer foot 56 be by connect projection 59 upper-lower positions adjustablely with link slot 58 bonded assemblys of base portion 52, so under the upper surface of the permanent magnet 44 of base portion 52 and state that magnetic sheet 38 is abutted against, the upper surface of each permanent magnet 57 around it can be abutted against with magnetic sheet 38, and adsorber 7 can lean on each permanent magnet 44,57 to be fixed securely.
Because each stabilizer foot 56 is to connect with it that projection 59 is desirable to be embedded in the link slot 58 of support 39 with taking off and to carry out bonded assembly, and is therefore simple in structure, make easily, it is also very convenient to get when taking off operation simultaneously.When stabilizer foot 56, permanent magnet 57 etc. sustains damage, replace also very convenient.
Because with the absorption cake 46 bonded assembly aspirate tubes 47 of each adsorber 7 is to be drawn out to support unit 37 with magnetic sheet 38 above and be connected tool 60 bonded assemblys with distribution from leadout hole 43 near each adsorber 7, so can prevent that aspirate tube 47 from hanging down.Extract frame 36 1 sides owing to distribute connection tool 60 to be positioned at, the aspirate tube 47 of each adsorber 7 is connected tool 60 and connects with this distribution, therefore be connected the situation that tool 60 is arranged at support unit 37 1 sides and compare with distributing, the position of distribution connection tool 60 can have nothing to do with the adjustment of operating panel and support unit 37 and maintain certain position, can improve its stability.
Because below support unit 37, adorning magnetic sheets 38 such as iron plate,, the whole installation weight that comprises support unit 37 alleviated so the thickness of magnetic sheet 38 can be thinner.Therefore, although support unit 37 is roughly the same fully to guarantee the setting range of adsorber 7 with bay-lift 5 with the size of magnetic sheet 38, the structure of crane 66 grades of supporting extraction frame 36 can be simplified.
After the adjustment end according to each parts such as 3 pairs of interval constraint plates 32 of printed circuit board (PCB), support unit 37 and adsorbers 7, then the setting by interval constraint plate 32 is loaded in 5 row substrate duplexers 4 on the bay-lift 5, allow its front end and baffle plate 31 be abutted against, carry out feeding then and supply with.
In this case, start lift motor 30, bay-lift 5 is risen, when above piece number is maximum in the 5 row substrate duplexers 4 the substrate duplexer 4 above the arrival during detection faces of detector 33, should measure this substrate duplexer 4 by top detector 33, lift motor 30 and bay-lift 5 are quit work.
Next, whenever whenever extract one piece of printed circuit board (PCB) 3 from each substrate duplexer 4, bay-lift 5 just rises successively, and substrate duplexer 4 top is controlled at certain level all the time.Like this, the printed circuit board (PCB) 3 above the absorption cake 46 absorption substrate duplexers 4 by adsorber 7 also highly can be kept its extraction that extracts roughly necessarily all the time, and this printed circuit board (PCB) 3 is adsorbed on the absorption cake 46 securely.
Bay-lift 5 one stops, and support unit 37 is under the state that is in bay-lift 5 top positions, and crane 66 descends because of the elongation action of lift cylinder 67, and extraction frame 36, support unit 37 are equal to this crane 66 with adsorber 7 and together descend.In other words, along with the decline of crane 66, the extraction frame 36 of its lower end, support unit 37, magnetic sheet 38 descend, and are contained in magnetic sheet 38 each following Adsorbing matter 7 by permanent magnet 44 and slowly descend.
When joining above the printed circuit board (PCB) 3 of the absorption cake 46 of each Adsorbing matter 7 and each substrate duplexer 4 upper, absorption cake 46 holds each substrate duplexer 4 uppermost printed circuit board (PCB) 3 by vacuum suction.Adsorber 7 is equipped with several below support unit 37, four adsorber 7 sorptions of one piece of printed circuit board (PCB) 3 usefulness.
When printed circuit board (PCB) 3 arrived the top of feeding belt conveyor 2, the absorption of 7 pairs of printed circuit board (PCB)s 3 of adsorber was disengaged.Like this, each printed circuit board (PCB) 3 is shifted on the feeding belt conveyor 2, is transmitted rearwards by this feeding belt conveyor 2, and simultaneously 5 printed circuit boards 3 of prining are transported to down the road matting.
Under 3 two pieces of situations about overlaping of printed circuit board (PCB), when the terminal part by feeding belt conveyor 2, detect roller 18 and rise, swing arm 19 press anticlockwise direction around bolster 16 and is swung, start non-contact switch 20, the feeding action of feeding belt conveyor 2 is stopped.
Figure 10～Figure 13 has represented the second embodiment of the present invention, and its stabilizing device S constitutes with permanent magnet.In this embodiment, the periphery of the base portion 52 of support 39 does not have stabilizer foot 56, and the outer peripheral face of base portion 52 is level and smooth cylindrical.In addition, base portion 52 also can be polygons such as hexagon, octagon.
The periphery of permanent magnet 44 is and the roughly the same ring-type of base portion 52 diameters, roughly becomes concentric shape along the circumferential direction to be embedded near the periphery of base portion 52 upper ends, and its upper end is more outstanding than the upper surface of base portion 52.The magnetization of permanent magnet 44 is with noted earlier the same.In this embodiment, stabilizing device S is made of permanent magnet 44.Protect the thin-walled shape protection portion of permanent magnet 44 to be wholely set from the outside with base portion 52.
This embodiment is the same with the above embodiments, and support 39 is fixed in magnetic sheet 38 by the suction of permanent magnet 44.But, because permanent magnet 44 is ring-types, be positioned near the periphery of base portion 52 of support 39, be roughly concentric shape at circumferencial direction and base portion 52, so the diameter of permanent magnet 44 is bigger because of the diameter of base portion 52.Like this,, also can be securely fixed on the magnetic sheet 38, can improve the stability of support 39 because of permanent magnet 44 makes support 39 even be subjected to laterally or the external force of hand of rotation is done the time spent at adsorber 7.
Owing to not have the thing outwards given prominence in base portion 52 1 sides of support 39, support 39 can miniaturization, and is very convenient with narrow arranged spaced adsorber 7 below magnetic sheet 38.Because permanent magnet 44 is ring-types, so even the external diameter of permanent magnet 44 is identical with the external diameter of support 39 base portions 52, permanent magnet 44 also can be with methods such as mould-formings easily and be securely fixed on the support 39.
Figure 14 and Figure 15 have represented the third embodiment of the present invention, and its stabilizing device S is made of the permanent magnet 44 of ring-type, also are embedded with another one permanent magnet 44c in the inboard of this permanent magnet 44 simultaneously.Like this, permanent magnet 44c is set, can increases total suction by inboard at permanent magnet 44.
Figure 16 and Figure 17 have represented the fourth embodiment of the present invention, and at the base portion 52 of support 39, permanent magnet 44 is cruciform arrangement, constitute stabilizing device S by this permanent magnet 44.The short magnet 44b that permanent magnet 44 has the roughly the same long magnet 44a of the diameter of length and base portion 52 and is disposed at these long magnet 44a length direction central authorities both sides.Long magnet 44a and short magnet 44b are embedded in the upper end of base portion 52, and its outer end roughly becomes a plane with the outer radial periphery face of base portion 52, and is the criss-cross by base portion 52 centers.The outer end of long magnet 44a and short magnet 44b is as long as near base portion 52 peripheries.Permanent magnet 44 also can be an one.
Because in this embodiment, permanent magnet 44 is also crossed over the radially two ends of support 39, so can fully guarantee the stability of support 39 being subjected to doing the time spent along the lateral external forces of permanent magnet 44 length directions or around the rotational force of the longitudinal axis.
Be the detailed description that embodiments of the invention are carried out above, but scope of the present invention is not limited to these embodiment.For example, in an embodiment, support unit 37 is that the heavy-gauge sheeting by aluminium and so on constitutes, below this support unit 37, adorning the magnetic sheet 38 that light sheet constitutes, but support unit 37 constitutes with regard to available magnetic material itself, with support unit 37 double as magnetic sheets 38 usefulness, also the enlarged in thickness of magnetic sheet 38 can be contained in its end on the support unit 37 with framed structure.In a word, as long as the structure that the permanent magnet 44,57 of support 39 and stabilizer foot 56 has by the magnetic force sorption.
